    Nasturtium microgreen varieties

    There are three different varieties of garden nasturtiums: dwarf, semi-trailing or trailing, and climbing. Dwarf species are short and dense. These types do not become vines and reach heights of 12 to 18 inches. As a result, they are the best type for growing as a microgreen.

    Nasturtium History

    Nasturtiums, often referred to as Indian Cress or Flame Flower, are perennial plants native to Columbia, Bolivia, and Peru. In the sixteenth century, they were found by Spanish conquistadors and taken to Spain.

    A variant called Tropaeolum minus, which had a little yellow blossom with a purple blotch, was the first Nasturtium introduced to Europe. This kind of nasturtium is currently quite scarce. The more well-known nasturtium, Tropaeolum majus, was first cultivated in the 1600s and became almost instantly famous due to its climbing ability.

    Nasturtiums quickly made a name for themselves as a delicious culinary delight; their peppery-flavored leaves and blooms could be used in salads, and their seeds, when preserved in vinegar, could be used as capers [1].

    High in antioxidants 

    Nasturtium microgreens have high concentration of lutein, an antioxidant linked to free radical defense and support for eye and skin health. 

    These microgreens contain vital vitamins and minerals, but also bioflavonoids (like myricetin, quercetin, and kaempferol derivatives) and beta-carotene. They also have high ORAC scores and contain trace elements and bioactive compounds, “which can be easily absorbed by the human body” (a form of vitamin A).

    Nasturtium microgreens’ apparent antioxidant activity appears to be attributed to their high concentrations of substances, including anthocyanins, polyphenols, and vitamin C. These attributes make them advantageous for the topically applied therapy of ailments affecting the skin, as well as the respiratory and digestive systems.
